The automotive world is filled with enthusiasts who are always looking for ways to enhance the performance of their vehicles. One of the most popular platforms for modification is the Mitsubishi Eclipse, particularly the first-generation models. In this article, we will explore how a $2,000 build on a 1G Eclipse resulted in an impressive boost to horsepower, reaching 300 HP.
Understanding the 1G Eclipse
The first-generation Mitsubishi Eclipse, produced from 1990 to 1994, is known for its lightweight design and turbocharged engine options. The base model features a 1.8L inline-four engine, but enthusiasts often opt for the turbocharged 2.0L version, which provides a solid foundation for performance upgrades.
The Build Plan
To achieve the goal of 300 HP, a strategic build plan was necessary. The budget of $2,000 required careful selection of parts and modifications that would deliver the best performance without breaking the bank. Here’s a breakdown of the key components involved in the build:
- Turbo Upgrade: Replacing the stock turbo with a larger unit for increased airflow.
- Fuel System Enhancements: Upgrading fuel injectors and pump to support higher horsepower.
- ECU Tuning: Custom tuning to optimize engine performance and fuel delivery.
- Exhaust System: Installing a high-flow exhaust to reduce back pressure.
- Intercooler Upgrade: A larger intercooler to improve charge air temperature.
Key Modifications Explained
Turbo Upgrade
The stock turbocharger on the 1G Eclipse is adequate for moderate power levels but can restrict performance at higher outputs. By upgrading to a larger turbo, such as a T28 or a Big 16G, enthusiasts can significantly increase horsepower. This upgrade allows for more air to enter the engine, leading to better combustion and power output.
Fuel System Enhancements
With increased airflow from the turbo upgrade, the fuel system must be capable of delivering more fuel. Upgrading the fuel injectors to a higher flow rate and installing a performance fuel pump ensures that the engine receives the necessary fuel to match the increased air supply. This balance is crucial for achieving optimal performance.
ECU Tuning
After upgrading the turbo and fuel system, the next step is to tune the engine’s ECU. Custom tuning adjusts the fuel maps and ignition timing to maximize performance based on the new modifications. This step is vital to ensure the engine runs efficiently and safely at higher horsepower levels.
Exhaust System
A high-flow exhaust system reduces back pressure, allowing exhaust gases to exit the engine more freely. This modification can lead to noticeable gains in horsepower, especially when combined with other upgrades. Popular choices include cat-back exhaust systems that improve both performance and sound.
Intercooler Upgrade
Upgrading the intercooler is essential for maintaining optimal air temperatures after the turbo. A larger intercooler improves cooling efficiency, which helps prevent knock and allows for more aggressive tuning. This upgrade supports the overall goal of reaching 300 HP while ensuring engine longevity.
Results of the Build
After completing the modifications, the 1G Eclipse was taken to a dyno for testing. The results were impressive, with the vehicle achieving 300 HP at the wheels. This power level not only enhances acceleration but also improves the overall driving experience. The combination of upgrades worked harmoniously to deliver the desired performance without compromising reliability.
Conclusion
The journey of building a 1G Eclipse to 300 HP for around $2,000 showcases the potential of budget-friendly modifications in the automotive world. With the right parts and a solid plan, enthusiasts can achieve significant performance gains without spending a fortune. This build serves as an inspiration for those looking to enhance their vehicles while staying within budget.
